2007 E92 335i Differential Carrier, no ring gear

Once I swapped this for a Wavetrac, I had no use for it. It's in very good shape and was removed from my car at ~55k miles. It has no ring gear or bearing races, and yes, this is a bolted diff. Get this out of my garage!

I've got no idea what to ask for it, so make an offer; just remember it's a bit heavy. If you've got a JB4 G5 laying around, I'd be interested in trading for that.

Total derp moment. Forgot to post the pics, and also to say this isn't the carrier, it's the differential itself (sometimes called the differential casing). I think I posted without thinking too hard. And here's a picture of it still in my pumpkin.
